You don't get to assault somebody because they call you a name. Racial or otherwise.
It might matter for Rudolph, but he completely denies it. It would be hard to imagine that a White football player while on the field in front of other football players, many of whom are Black, would use a racial epithet. Not saying it's impossible, but so very unlikely. There better be audio proof because otherwise this playing of the race card out of convenience is getting awfully old to many of us.
Garrett is looking pretty bad at this time.
